BitBarista

BitBarista

Bitbarista is a Bitcoin powered coffee machine.

Digital Catapult’s IoTUK programme is working with PETRAS, the university consortium studying privacy, ethics, trust, reliability, acceptability, and security in the Internet of Things.

In this case study, we take a closer look at BitBarista.

What is BitBarista?

Bitbarista serves you coffee in exchange for a Bitcoin contribution towards its future coffee supply. The coffee beans used to make your coffee served will have been selected collectively by previous customers.

In order to assist customers in considering future supplies Bitbarista displays data on the state of coffee-producing countries looking for information on climate, work conditions, political situation, infrastructure, price stability and demand, which the machine browses online.

From this data the machine selects top-ranked options for coffee beans in four categories: best quality, lowest price, lowest environmental impact and highest social responsibility. It then offers users the opportunity to choose one of these options for its next supply, and customers pay for their coffee accordingly. After the purchase, a new screen situates the choice within the pool of choices previously made, all anonymised, displaying the supply most likely to be ordered next. The aim of this interaction is to create transparency around the process of engaging with coffee supply chains, with the intention of creating a positive experience of data sharing in this context.
